Tiers name what a vendor publishes, not a verdict on any product's purity or quality. Lab-verifiable COAs: certificates that open on the testing lab's own site (the seal's ring shows what share of them do). Third-party COAs: certificates attributed to a third-party lab, which may be hosted only on the vendor's site. Tiers follow the Vendor Score (90+ and 80–89), which is 87% COA evidence; the numeral in each seal is that score. Affiliate relationships never affect tiers, selection or order. How the Vendor Score works
IGF-1 LR3 (Long-R3 insulin-like growth factor-1) is an 83-amino-acid analog of human IGF-1, modified by an arginine substitution at position 3 and a 13-residue N-terminal extension that reduce its binding to IGF-binding proteins. It is a research peptide studied in laboratory and cell-culture models of growth-factor signaling, cell proliferation, and receptor biology. This index tracks research-use-only (RUO) vendor pricing for IGF-1 LR3 so researchers can compare cost across suppliers.
Evidence brief
IGF-1 LR3 (Long R3 IGF-1) is a modified insulin-like growth factor-1 analog with reduced binding to the IGF-binding proteins, used chiefly as a laboratory research reagent.

Per-mg pricing for IGF-1 LR3 varies widely because vendors differ in synthesis or recombinant expression method, stated purity, vial fill size, and lot testing rigor. Comparing normalized $/mg across suppliers helps a researcher weigh cost against documented quality rather than paying a premium for equivalent material.
For IGF-1 LR3, confirm identity by mass spectrometry against the expected mass of roughly 9.1 kDa for the 83-residue analog, and check that the sequence reflects the Arg3 substitution and the N-terminal extension rather than native IGF-1. Look for an HPLC purity figure (commonly >=95-98%) and scrutinize the impurity profile for truncated or misfolded species and deamidation products, since incorrect disulfide folding can yield material that fails functional or identity verification despite having the same nominal mass. A legitimate COA is lot-specific and should also state endotoxin and, ideally, residual solvent or counterion content.
